A year or so ago I tried to cut this model up so that it would print easily and the supports wouldn't leave a mark with little luck. Flash forward to now when I've learned a lot more about printers and Fusion 360 and this model prints beautifully, supports are minimal and pop right off and it's a fast print. There are 3 dowels used to position the two halves, and I used a little superglue to hold them together. Note, you can upscale or downscale the dowels if they aren't exactly the size you want.
 

I also created a hanger that will work nicely with them and can connect multiples together.
